FRAMEWORK OF MULTISTORIED BUILDING Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: framework of multistoried building of various purpose to be erected in various regions including seismic has columns with through-openings at level of floor disks. Floors are made up of reinforced concrete integral load-bearing span-pieces which are orthogonally conjugated in common plane with reinforced concrete connecting span-pieces and multiple-core floor slabs. Ends of load-bearing span-pieces are made in the form of wedges which are located in opening of extreme columns and with their narrow part are directed inside building. In openings of middle columns, integral load-bearing span-pieces are made in the form of double wedges which with their narrow part are directed towards each other and towards axis of columns. Longitudinal through-type working reinforcement of connecting span-pieces is made of constant cross-sectional area over length of each span. Reinforcement is anchored behind columns and is arranged over lower plane of cross-sectional area of connecting span-pieces. Amount of reinforcement in each span is determined by relation given in description of invention. Framework for multistoried building simplifies manufacture, reduces number of type-sizes of assembling articles to two types of multiple-core slabs and one type of column, with reduction of labour needed for erection. EFFECT: higher efficiency. 2 cl, 15 dwg
